CIRCUIT AND CONSTRUCTIONAL ARRANGEMENT FOR TWO-WAY WIRELESS INFORMATION TRANSMISSION BETWEEN DIFFERENT UNITS OF INDUSTRIAL CONTROLLING AND PROCESS CONTROLLING DEVICES ON ROTATING/DEAD-SHAFT

摘要

The invention relates to a circuit and a construction arrangement for bidirectional wireless transmission of information, through rotating/stationary axes between different units of industrial actuating and process control equipment said arrangement incorporating two information forwarding, transmitting and converting main units (IA, IB) preferably of identical design, each consisting of a power supply unit (1A, IB), an optical receiver unit (2A, 2B), a direction coupling unit (3A, 3B), and an optical transmitter unit (4A, 4B), where the optical transmitter unit (4A) located in one of the two information forwarding and converting main units (i.e. IA) constitutes a transmission channel with the optical receiver unit (2B) located in the other information forwarding and converting main unit (IB) while the optical transmitter unit (4B) located in the other information forwarding and converting main unit (IB) constitutes a transmission channel with the optical receiver unit (2A) located in said one of the two information forwarding and converting main units (i.e. IA).
